Abstract
A data communication system comprises a central office processor which comprises a first input mapping unit, a first wave-front multiplexer, and a first output mapping unit. The first input mapping unit receives and dynamically maps digital data into a plurality of first electronic signals. The first wave-front multiplexer is coupled to the first input mapping unit to receive the first electronic signals, perform a wave-front multiplexing transformation on the first electronic signals, and output wave-front multiplexed signals, each of the wave-front multiplexed signals being a linear combination of the first electronic signals. The first output mapping unit is coupled to the first wave-front multiplexer to receive and dynamically map the wave-front multiplexed signals into second electronic signals.
